Tungsten Heavy Alloy Rod
1. What's Tungsten Heavy Alloy Rod?
Tungsten heavy alloy rod, also known as tungsten alloy rod, is a tungsten-based heavy alloy rod manufactured through powder metallurgy, using tungsten as the primary phase and adding nickel (Ni), iron (Fe), or copper (Cu) as binder phase elements. With tungsten content typically ranging from 90%–97%, it achieves high density, high strength, and good machinability. Its density can reach 17.0–18.8 g/cm³, providing a high mass-to-volume ratio and stable physical properties. CTIA’s tungsten heavy alloy rod mainly includes tungsten-nickel-iron (W-Ni-Fe) and tungsten-nickel-copper (W-Ni-Cu) series, widely used in aerospace counterweights, radiation shielding, inertia control, precision manufacturing, and high-end equipment applications.
2. Characteristics of CTIA’s Tungsten Heavy Alloy Rod
(1) High Specific Gravity
The alloy provides high density, enabling greater mass within limited space and making it suitable for weight adjustment and counterweight applications in space-constrained environments.
(2) Good Mechanical Properties
The alloy features high strength, hardness, and wear resistance, with tensile strength typically ranging from 700–1000 MPa, meeting long-term load-bearing requirements.
(3) Stable Physical Properties
The alloy has a coefficient of thermal expansion of approximately 4.5–5.5×10⁻⁶/K and maintains good dimensional stability under temperature variations, making it suitable for precision equipment and complex operating conditions.
(4) Good Machinability
The alloy provides improved toughness compared with pure tungsten materials and can be precision machined through turning, grinding, and other processes for complex structural components.
(5) Excellent Radiation Shielding Capability
The alloy utilizes tungsten’s high atomic number (74) and high density to provide effective absorption of X-rays and gamma rays.
